 Hey guys, this is Kevin. This video is add-on to the previous video. I told you if I have a clog, try to use the absence building function to unclog it at least 9 to 10 times to not give up in the middle. This is because absence self-cleaning is not that effective. So maybe your clog is not that bad. It just absence is not efficient. The reason that absence of prenat cleaning is not really effective is it doesn't have a real ink pump to suck it. Let me show you. This is from the rubber that seals the bottom of the prenat. Underneath there's a tube, actually there are two tubes that are connected to this pump that sucks ink out of the prenat. The problem is this is not a real pump. If you look inside, it uses a gear to wind this tube. So when the tube is unflattened, it creates a little bit of suction to suck the ink out of the prenat. So the whole force is generated by this tube. You can see the suction was really, really weak. I calculated you probably get a good suction every third time you clean the prenat. So there are lots of people just do the cleaning once or twice and then just give up. When they give up, they put the printer on Facebook Marketplace or eBay and that's the time you're going to strike. I got this eco tank from eBay for next to nothing. Yeah, I did pay for the shipping but the printer itself is almost free. The printer's owner said the printer is for parts because it's clogged. The owner said, hey, I'm clogging it multiple times, at least five times. So I decided to get it and so I can show you that you can fix it just by repeatedly cleaning it. So to clean it, you just go left and right, go to maintenance and go to head cleaning and just click OK and it's going to print out this head cleaning page. And the big surprise to me is this seller already printed 18,000 pages. So I was worried that this is not because of clogging, it's because the printer has clogged out and burned out. So I start cleaning. So I have this number increased one page. You can see this is the first cleaning, second, third. And also you can see at the third cleaning, the sign gets more color but the yellow is missing again. This is actually a good sign. What I found is if it's really consistent, exactly the same thing all the time, that's not a good thing. So if it comes back and forth, you're more likely to unclog it. The first one, as I see, all the color is completely gone. The owner probably put it down the ebay after fifth cleaning. Now it looks like the cold color is completely gone. Six. And I got a yellow bag. I almost gave up by then because I space. I thought maybe just put this printer away and stop it to pass. I really need a space. I think let's do like one or two more times because I normally stop at nine. Seven. Oh and the seven, the magenta is coming back. I get a perfect other three colors and I'm excited. And this is number eight. Perfect, perfect, perfect, perfect. So the take-home message is run the head cleaning nine times before you try some more aggressive methods to unclog it.
